Good day fellow forum members,
I have a 1981 Lund guide special (15’) fiber glass tri-hull 35 hp Johnson 20" shaft paired with 10.5” x 11” prop.
I’m having issues getting it to plane. Main performance issues are that it’s slow to plane, there’s a fair amount of bow rise and struggles to plane with more than one passenger/won’t plane if I exceed 80-85% of the boats load capacity. There’s a chance I could be overloading the boat, not sure if motor weight is included in maximum boat weight capacity? Figure I need more lift at the stern, the boat is aft heavy with the motor, gas tank, battery, steering console and myself all sitting in the back 3-4ft of the boat.
Debating first course of action between these 3 options:
Four blade aluminum prop
Engine-mounted hydro foil
Pair of smart tabs
Anyone have similar experience or ideas to solve the issue? My only experience is electric trim tabs on a 24’ Sea Ray.
Thanks in advance for your help. Can’t wait to hear back. Sitting on the edge of my dock waiting for the first reply!
